摘要： Methods and systems selectively irradiate structures on or within a semiconductor substrate using a plurality of laser beams. The structures are arranged in a row extending in a generally lengthwise direction. The method generates a first laser beam that propagates along a first laser beam axis that intersects the semiconductor substrate and a second laser beam that propagates along a second laser beam axis that intersects the semiconductor substrate. The method simultaneously directs the first and second laser beams onto distinct first and second structures in the row. The method moves the first and second laser beam axes relative to the semiconductor substrate substantially in unison in a direction substantially parallel to the lengthwise direction of the row, so as to selectively irradiate structures in the row with one or more of the first and second laser beams simultaneously.

摘要： A method for calibrating a laser micro-machining system in three dimensions includes scanning a sample workpiece to determine the 3D surface, calculating the best fit surfaces to the scanned data in a series of steps, and storing the results so that subsequent workpieces can be calibrated to remove systematic errors introduced by variations in an associated material handling subsystem. The method optionally uses plate bending theory to model particulate contamination and splines to fit the 3D surface in a piecewise fashion to minimize the effect of local variations on the entire surface fit.

摘要： Laser beam positioners (300, 340) employ a steering mirror (236, 306) that performs small-angle deflection of a laser beam (270) to compensate for cross-axis (110) settling errors of a positioner stage (302). A two-axis mirror is preferred because either axis of the positioner stages may be used for performing work. In one embodiment, the steering mirror is used for error correction only without necessarily requiring coordination with the positioner stage position commands. A fast steering mirror employing a flexure mechanism and piezoelectric actuators to tip and tilt the mirror is preferred in semiconductor link processing (“SLP”) applications. This invention compensates for cross-axis settling time, resulting in increased SLP system throughput and accuracy while simplifying complexity of the positioner stages because the steering mirror corrections relax the positioner stage servo driving requirements.
摘要翻译：激光束定位器（300,340）使用执行激光束（270）的小角度偏转以补偿定位器台（302）的横轴（110）沉降误差的转向镜（236,306）。优选两轴镜，因为定位器台的任一轴可用于执行作业。在一个实施例中，导向镜仅用于纠错，而不需要与定位器台位置命令协调。在半导体连接处理（“SLP”）应用中，优选采用挠曲机构的快速转向镜和压电致动器来使倾斜反射镜。本发明补偿横轴建立时间，从而提高了SLP系统的吞吐量和精度，同时简化了定位器台的复杂性，因为导向镜校正放松了定位器级的伺服驱动要求。
